Anthracnose and berry disease of coffee in Puerto Rico
A survey revealed that anthracnose (Glomerella cingulata asex. Colletotrichum gloeosporioides) was the principal aboveground disease of field coffee in Puerto Rico. Isolates of C. gloeosporioides from both diseased soya beans and coffee caused anthracnose after in vitro inoculation. Necrotic spots on coffee berries collected from the field were associated with C. gloeosporioides the eye spot fungus (Cercospora coffeicola) and the scaly bark or collar rot fungus (Fusarium stilboides). Double fertilizer application (454 g 10-5-15 NPK with micronutrients/tree/3 months) appeared to reduce the number of diseased berries by approximately 41 and fungicide sprays (benomyl + captafol) gave 57 control. Combining high rate of fertilization and fungicide applications resulted in a reduction of approximately 85 of diseased berried
